Messiah (HWV 56) is an oratorio by George Frideric Handel based on a libretto by Charles Jennens. Composed in the summer of 1741 and premiered in Dublin on the 13 April 1742, Messiah is Handel's most famous creation and is among the most popular works in Western choral literature. The very well-known chorus "Hallelujah" is part of Handel's Messiah.
